Simplify the expression $\displaystyle-{6}{x}\div{3}=\frac{{-{6}{x}}}{{3}}=-{2}{x}\usepackage{cmbright}\Huge\$

Substitute $\displaystyle\frac{{3}}{{4}}\usepackage{cmbright}\Huge\$ for x in the expression. $\displaystyle-{2}{x}=-{2}{\left(\frac{{3}}{{4}}\right)}=-{\left(\frac{{6}}{{4}}\right)}=-{1}\frac{{1}}{{2}}\usepackage{cmbright}\Huge\$
